Adventure Time Season 10 Episode 4 - Bonnibel Bubblegum Episode Title:Bonnibel Bubblegum.Episode Description:When Finn presents the silver cup from "Always BMO Closing", Princess Bubblegum decides to tell him, Marceline and Jake more of her history. Eight hundred years ago, Bubblegum decided to create a gum family—composed of Uncle Gumbald, Aunt Lolly and Cousin Chicle—to help farm the area. However, her family quickly turned on her, as Bubblegum resisted Gumbald's efforts to "brand" their family and create a capitalist empire. Gumbald decided to stage a coup by dousing his niece with a juice which transforms its drinkers into low-minded candy people. Bonnibel fought back, and in the ensuing mayhem, Uncle Gumbald, Aunt Lolly and Cousin Chicle were all transformed into the first of her candy citizens. In the present, BMO reveals that it got the cup from a recently-return Gumbald.
